- 11 Claims. 1

This invention relates to storm windows an has for an object to providean all weather window that has a permanently mounted screen therein andan inner glass sash that is adjustable from a position covering thescreen to a D- sition in which the screen is uncovered.

It is also an object of the invention to provide a window in which thesashes are securely fastened against tampering from the outside.

A further. object of the invention is to provide a window of thecharacter referred to that is effectively weatherstripped.

An additional object is to provide weatherstrips between the sashes andthe sash frame that are put under pressure by outward-pressure appliedto the sashes.

A further object of the invention is to provide a window in which thesashes are so mounted that they may be readily removed from the insidefor cleaning.

With the above and other objects in view, the invention may be said tocomprise a storm window as illustrated in the accompanying drawings,hereinafter described and particularly set forth in the appended claims,together with such variations and modifications thereof as will beapparent to one skilled in the art to which the invention pertains.

Reference should be had to the accompanying drawings forming a part ofthis specification, in which:

Fig. 8 is a section on an enlarged scale taken on the line indicated at88 in Fig. 1, and

Fig. 9 is a section on an enlarged scale taken on the line indicated at9-9 in Fig. l.

The window of the present invention is composed of a sub-frame A that isadapted to be mounted in a window opening, a sash frame B that ismounted in the frame A, and sashes C, D, and E which are mounted in thesash frame, the

sashes C and D being superimposed one upon the other and filling theopening of the frame '3 and the sash E being slidably mounted in frame Binside the superposed sections C and D. The lower sash C carries ascreen while the sashes D and E are glass sashes, the inner sash E beingof a size to cover the screen and being adjustable to a position clearof the screen.

The sub-frame A is formed of inwardly facing sheet metal channels I thatare secured by suitable means against window stops 2 of a windowopening. The sash frame 13 has tubular sheet metal jambs 3, a tubularsheet metal head rail 4 and a tubular sheet metalsill 5. The jambs 3have stop flanges 6 formed along the outer edges of their interior facesI which are flat, in-

' wardly of the flanges 6. The head rail 4 has a stop flange 8 along theouter edge of its interior face 9 which is flat, inwardly of the flange8. The flanges 6 and 8 of the sash frame lie in the same plane andprovide stops for the sashes C and D. The sill 5 has a depressedinclined sash seat l0 and a stop shoulder II at the rear edge of theseat ID. The lower sash C has tubular sheet metal stiles l2 and tubularsheet metal top and bottom rails l3 that are of substantially identicalform. The stiles l2 and rails i3 are formed to provide outwardly openingchannels I adjacent their inner edges and a wire screen l5 has marginaledges extending into the channels it and held therein by means ofretaining strips 16 that have wedging engagement with the wire fabric.

The sashes C, D, and E are preferably of the same size and the innersash E and the upper sash D may be of identical construction. Sashes. Dand E have tubular sheet metal stiles I1 and tubular sheet metal top andbottom rails l8 that are of identical form and each has a stop flange l9at the outer edge of its interior face. Inwardiy of the stop flange ISthe stiles and rails have inwardly facing channels 20. A glass panel 2|is mounted in each of the sashes D and E and these panels are held inplace by retaining strips 22 which are resilient sheet metal stripsprojecting into the channels 20 and resiliently pressing the panels 2|against sealing strips 23 positioned between the glass panes and thestop flanges 19.

The stiles 12 of the sash C and the stiles l1 and rails 18 of the sashesD and E are formed with outwardly facing channels 24 adjacent theirouter edges. Weatherstrips 25 are mounted in the channels 24 of thestiles of the sash C, the stiles and top cross rail of the sash D and inall of the asoaasa channels 24 of the inner sash E. The weatherstrips IIof sashes C and D bear against the stop flanges I and l of the jambs andhead rail of the frame B and the strips 2| of the sash E bear againstthe stiles of the sashes C. and D and the bottom rails of the sashes Cand D, the weatherstrips 2! of vthe inner sash E forming. a sealextending entirely around the screen when the sash E is in its lowermostposition.

The channel 24 of the bottom rail of the sash D has a drip strip"mounted therein. The strip 28 projects outwardly from the rail is andis inclined downwardly to deflect water from the space between thesashes C and D, the strip 2' being detachably held in place by theresilient expansible portion I! that engages in the channel ll. a

The stop flanges of the jambs 3 extend to th sash seat ll of the sill 5and the two sashes C and D are of a size to substantially fill theopening of the frame 3 inwardly of the stop flanges 8 and I. Sumcientclearance may be provided between the head rail lgand the top sash D topermit the screen fram C to betilted inwardly until its top edge clearsthe bottom edge of the sash D, after which it may be lifted out... Aresilient angle stop 28 is secured to the interior face of the head rail4 by suitable means such as a screw 29. The stop 28 has an aperture IIIthat receives a lug 3| projecting from the inner face of the top rail llof the sash D. After removal of the sash C the stop 2! will yieldsufficiently when the sash'D is pulled downwardly to release v the lugII and free the sash.

In order to provide a weather-tight connection between the sashes C andD and the sash frame 3, means is provided for pressing the sashes C andD against the stops i and l. The sash holding means is in the form ofstops 32 that are mounted on the jambs 3 slightly above the midpointbetween the upper and lower ends thereof, The stop members 32 are formedof resilient sheet metal and have laterally extending attaching portions33 that are attached to the inner faces of the jambs 3, and upwardly anddownwardly extending resilient arms 34 that project into the sashframeop ning and normally bear against the stiles of the sashes C and D. Asshown in Figs. 2, 3 and 4, the arms 34 are adapted to be swung outwardlyto receive the inner sash E between them and the superposed sashes C andD. Adjacent the lower ends of the jambs 3, stop plates 35 are attachedwhich are spaced at considerable distance beyond the lower ends of thedownwardly extending arms 34, the stop plates 35 having inwardlyinclined upper edge portions 36 to facilitate'the entry of the sash Einto the space between the stops 35 and the stiles II of the sash C.

As shown in Fig. 3, the upper edge of the sash 4 gagement with the sill,so that the lower edgelof C. When the sash E is in its lowermostposition,

its upper end is pressed toward the bottom rail of the top sash E by thedownwardly projecting spring arms 34, so that all of the weatherstripsII carried by the sash 'E are held under sufficient pressure to providean effective seal extending entirely around the screen. At the same timethe upper spring arms 34 press against the inside of the top sash D topress its weatherstrips ll against the stop flanges 8 and I. Handles IIare pivoted to brackets 38 attached to the bottom rail ll of the innersash E and these handles are adapted to hook over pins Ill attached tothe sill I to normally retain the sash E in its lowermost position. Thesash C may" be provided with handles ll to facilitate its removal fromthe frame.

For permanently closed windows the screen sash C is not desirable. Thesashes C, D, and E are preferably of the same size so that when desiredthe screen sash C may be removed and re-.

placed by the glass sash E. Regardless of whether the three sashes aremounted in the frame 13 or whether the two glass sashes are mounted inthe frame the sashes are effectively weatherstripped by reason of theoutward pressure of the spring stops 3! acting upon the weatherstrips28.

The storm window frame per se is claimed in my copending applicationSerial No. 69,488, filed January 8, 1949.
